It’s another big week for Nintendo’s download services… and we even get another Wii U game.

That game is Gaijin Games’ Bit.Trip Presents Runner 2: Future Legend of Rhythm Alien. The platformer, which stars everyone’s favorite monochrome mascot, CommanderVideo, is available today is both demo and full version form.

Also available this week is Konami’s Castlevania: Lords of Shadow – Mirror of Fate. The 3DS side-story that bridges the gap between the two Lords of Shadow games on the PS3/Xbox 360 is available now as a demo, with the full game set to hit the 3DS eShop on Tuesday, March 5.

Finally, this week finally marks the release of Retro City Rampage on the Wii Shop Channel. An 8-bit-styled, open-world game reminiscent of Grand Theft Auto’s early days, Retro City Rampage on the Wii includes the special “ROM City Rampage” mode, which morphs the game into a true 8-bit adventure that would have worked on the NES.

Hit the jump for more details on all of these games as well as three other additions to this week’s Nintendo Download.
